A randomized controlled study comparing guided bone regeneration with connective tissue graft to reestablish buccal convexity at implant sites: A 1‐year volumetric analysis

Objectives To volumetrically compare guided bone regeneration (GBR) with connective tissue graft (CTG) to reestablish convexity at the buccal aspect of single implants. Materials and methods Patients with a single tooth gap in the anterior maxilla and horizontal alveolar defect were enrolled in a si...

Description
Summary:Objectives To volumetrically compare guided bone regeneration (GBR) with connective tissue graft (CTG) to reestablish convexity at the buccal aspect of single implants. Materials and methods Patients with a single tooth gap in the anterior maxilla and horizontal alveolar defect were enrolled in a single‐blind randomized clinical trial (RCT). All sites had a buccopalatal bone dimension of at least 6 mm, received a single implant, and were randomly allocated to the control (GBR) or test group (CTG) to reestablish buccal soft tissue convexity. Patients received a provisional crown at 3 months and a permanent crown at 6 months. Primary outcomes were volumetric increase (mm3) and linear increase (mm) in buccal soft tissue profile (BSP) within a well‐defined area of interest at fixed time points. Alveolar process deficiency was a secondary outcome. Results Twenty‐one patients were included per group (control: 11 females, mean age 51; test: 9 females, mean age 48). After 1 year, GBR resulted in a significant volumetric increase of 20.74 mm3 (P
